DROP-TABLE FOR SEWING-MACHINES.

Application filed May 22, 1914, Serial No. 840,264.

To all whom it may concern:

Be it known that I, CARL LABORENZ, a

subject ofthe German Emperor, and residin at 107/109 Knesebeckstrasse, Berlin- Neukolln, Germany, manufacturer, have invented certain new and useful Improvements in Drop-Tables for Sewing-Machines, of which the following is a statement.

The present invention relates to a drop table top made in one piece for carrying the upper part of a sewing machine, in which table top a longitudinal sliding boltis arranged to slide in such'a manner, that when the table top is raised, it is supported at two points simultaneously, so that, while the machine is being used, its steadiness is not impaired.

In the accompanying drawing the new drop table top for sewing machines is exemplified.

Figure 1 is a side elevation of the sewing machine with the upper part in operative position. Fig. 2 is a corresponding top view, and Figs. 3 and 4 are side and top views of the sliding bolt and its neighboring parts.

To the underside of the frame of the table a is hinged by means of hinges b and c the top f carrying the upper part of the sewing machine d. In this top f is guided a bolt 9 disposed in a recess and under action of a spring h. I On the underside of the frame a I an angular stop 71 is secured, against which Specification of Letters Patent.

Patented Dec. 21, 19 15.

Renewed November 13, 1915. Serial No. 61,444.

- the one end of the bolt 9 will slide, when the top f with the sewing machine is raised;

Over the angle z a recess is provided in the wood of the frame a, into which recess the bolt 9 enters under action of the spring h, as soon as the top f has reached the same level as the frame of the table. At the same time the bolt 9 will rest on thebearing is in the frame a, which bearing 74 can pass through the notch m in the bolt 9 when the latter has been withdrawn by hand by means of the knob Z, so that the top plate can drop. I

I claim: v

In a drop head sewing machine, in combination with therecessed frame thereof, a drop table top hinged to said frame and provided with a groove on its underside, a spring controlled, recessed bolt within said groove, a support for said bolt, an angular stop secured to the underside of the frame and providing a beveled approach to the re cess in said frame, the recess of said bolt permitting the passage of said support dur ing the upward movement of the tabletop, substantially as described.

In testimony whereof I aflix my signature in presence of two witnesses.
